"I placed an order to EAI Education via internet on March 14th and was pleasantly surprised to find the merchandise that I ordered sitting at my back door when I got home from school today. I am so impressed with the promptness of your company! This was the second time that I have placed an order with you and I will definitely be ordering from you again in the near future. Keep up the good work!-- Tamara C., Maine

Description

Great for supporting the development of number sense, rekenreks are visual models that encourage students to subitize, think of numbers in groups, strengthen counting proficiency, develop addition and subtraction strategies, and gain a better understanding of number relationships. Use the Ten-Bar Rekenrek with Color Change Classroom Set to practice addition, subtraction, and counting up to 100.

The units feature 10 bars, each containing 10 beads (100 beads total). The bead color changes after the first five beads. On the top five bars the beads change from red to white, and on the bottom five bars the beads change from white to red. The inner and outer faces of the frame on the Demonstration Rekenrek are painted blue for easier visibility. The demonstration unit measures 20 3/4" × 5 1/2" × 15 3/4". The student units measure approximately 13"H × 2 3/8"W.
